摘要:
An object of the present invention is to reduce the thickness of a lighting device using an electroluminescent material. Another object of the present invention is to simplify the structure of a lighting device using an electroluminescent material to reduce cost. A light-emitting element having a stacked structure of a first electrode layer, an EL layer, and a second electrode layer is provided over a substrate having an opening in its center, and a first connecting portion and a second connecting portion for supplying electric power to the light-emitting element are provided in the center of the substrate (in the vicinity of the opening provided in the substrate).
